Lots of signals protect this little line. Two cantilevers protect the main road. The cantilever lights are 12"x24" incandescent lights with 2 mechanical bells total: One on each gate.

 

There's also two gateless signals guarding a side street as seen in pictures 1, 3, and 8. The closest signal in picture 3 is 12"x20", while the other gateless signal across the street is 12"x24". Both of those signals have incandescent lights.

Another shot of both cantilever signals.
